ELECTRICAL. WATER- H EATER.

SPECIFICATION forming part of Letters Patent N 0. 727,360, dated May 5, 1903. Application filed March 31,1902. Serial No. 100,740) (No/model.)

fo @ZZ whom, t Worry concern.-

Beit known that I, HARRY M. HILL, a citizen of the United States, residing at St. Louis, State of Missouri,haveinvented acertain new and useful Improvement in Electrical Water- Heaters,of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in Which- Figure 1 is a side elevational View of my improved electrical water-heater. Fig. 2 is a vertical sectional View through the same. Fig. 3 is across-sectional view on line 3 3 of Fig. 2. Fig. 4 is an elevational view of one of the electrodes. Fig. 5 is au elevat-ional view of the other electrode, and Fig. 6 is a bottom plan view of the centering-disk.

This invention relates to a new and useful improvement in electrical water-heaters of that class shown in United States Letters Patent No. 678,314,granted to me July 9, 1901. My present invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

In the drawings, 1 indicates a stand-pipe for water, the same being arranged in an ordinary pipe system. r The upper end of this stand-pipe is shownas being curved to form a gooseneck, the end thereof carrying a spigot 2, manipulated by a handle 3.' The spigotstem is provided with a key 4, fitting in a slot in a switch-stem 5, said switch being inclosed in a casing 6, supported by a bracket 7 upon the stand-pipe.

Referring to Fig. 2, 9 indicates a coupling which is screwed in the lower end of the spigot, into which coupling is fitted a head 11,made of insulation material. 12 indicates a flanged boss secured to the under side of the head 11, said coupling 9, head 11, and iianged boss 12 being provided with alining openings for the passage of water. A wire 8 leads to the flanged boss 12. The purpose of thus separating the coupling 9 and the flanged boss 12 is to insulate the apparatus from the water-pipe.

13 indicates an electrode, which for the sake of distinction will be termed the inner electrode,the same being provided with a bore for the passage ot' water, whereby the water is caused to pass downwardly through this inner electrode and be distributed by means of a cen tering-head 14, of insulation material, at different points outside of the central or core electrode.

The insulation centering-disk referred to is preferably screwed into the lower end of the electrode 13 and is provided with radial P u l n grooves 15 on its underface, (see Fig. 6,)

which connect with vertical Vside grooves 16 at its periphery. (See Figs. 2 and 5.) In this manner the water is distributed around the periphery of the centering-disk and directed upwardly at different points outside of the central electrode.

17 indicates what I will term an outer or encircling electrode,which is preferably formed with an imperforate bottom, as shown, and an inner bore whose diameter corresponds to the diameter of the insulation centeringdisk 14. In this manner the electrode 17 forms the bottom and side walls for the grooves 15 and 16, respectively. The upper end of electrode 17 is open for obvious reasons and is designed to abut against the under face of the insulation head 11. Openings 18 are formed in the side walls of electrode 17 near its upper end for the escape of water passing between the inner and outer electrodes.

The outer side face of electrode 17 is corrugated or provided with a series of grooves 19, (see Fig. 4,) the external diameter being reduced at the upper end of said electrode 17 to form shoulders 20, which support an imperforate hood-ring 21. This ring or band 21 extends above the upper end of electrode 17 and is received in a concentric groove 22 in the under face of' the insulation-head 11. A

wire 23 is connected to this band for supply- IDO centric groove 26 in the insulation-head l1, said housing being of larger diameter than the outer electrode, so as to provide a passage for the heated water. This housing is slotted for the reception of thimble 2-1, as shown at 27 in Fig. 2, and when the housingis in position screws-2S (see Fig. l) are employed to hold-said housing in place. 'Y

In operation the act of admitting water to the heater by turning the spigot throws a switchandcompletesthecircuit. lVaterpassing through the bore in the central electrode is distributed by the centering-disk at different points between the inner and outer electrodes, where it is heated, the water then rising and overflowing through the lateral openings 18. Striking the band 2l it is directed downwardly into the housing 25, which housing serves as a funnel to collect the heated water and discharge it through the opening in its bottom. The upper end of the housing opens to atmosphere through the slot 27, and consequently there is no danger of steam generated by the heated water forming a trap and exerting a back pressure to interfere with the operation of the device.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an electrical water-heater, the combination with an outer electrode, ot an inner electrode therein, both of said electrodes having water-passages therethrough, and a dischargesheli surrounding said electrodes, forming therewith a water-channel, between said outer electrode and said shell; substantially as described.
